Wedoany.com Report-Dec.12, Johnson Matthey has officially opened a dedicated hydrogen internal combustion engine (H₂ICE) testing centre at its established site in Gothenburg, Sweden. The new facility, the company's first focused on this technology, specialises in emission control systems for heavy-duty hydrogen-powered engines and enables full-engine testing rather than component-level evaluation alone.

The Gothenburg installation can handle engines up to 600kW (800hp).

The £2.5 million ($3.34 million) investment, delivered over three years, was completed on schedule and within budget. It targets medium- and heavy-duty vehicles such as buses and trucks, supporting the use of hydrogen as a zero-carbon fuel within conventional internal combustion engine designs.

Johnson Matthey's chief technology officer for clean air, Tauseef Salma, stated: "This investment shows Johnson Matthey is backing H₂ICE as a ready-to-go technology that will enable mobility partners to meet their decarbonisation and climate goals. Our state-of-the-art Gothenburg facility positions Johnson Matthey as a world leader in sustainable technology solutions, transforming energy and reducing carbon emissions."

The centre can accommodate engines up to 600 kW (800 hp) and includes comprehensive on-site hydrogen infrastructure: a compressor, intermediate storage tank, high-pressure storage up to 413 bar, precise flow metering, exhaust gas analysis equipment, and advanced safety and control systems. It complements existing test cells for medium- and heavy-duty diesel engines already operating at the Gothenburg location.

The expanded capability is designed to support customers in the transport sector as global emission regulations tighten and demand grows for practical low-carbon propulsion options. Hydrogen internal combustion engines offer a familiar architecture for manufacturers while delivering zero tailpipe CO₂ emissions when fuelled by green hydrogen.

The Gothenburg H₂ICE facility builds directly on Project Brunel, a collaborative research programme launched in November 2021 with Cummins and partners PHINIA and Zircotec. That initiative, completed in March 2025, demonstrated measurable advances in hydrogen engine efficiency, performance, and long-term durability.

The official inauguration was conducted by Johnson Matthey R&D director Damien Sotty, Gothenburg Test Centre manager Daniel Sandqvist, and Jonas Edvardsson, managing director of Johnson Matthey Gothenburg. With this investment, the company strengthens its portfolio of decarbonisation technologies, providing vehicle and engine manufacturers with proven after-treatment solutions tailored for the emerging hydrogen combustion market.
